Faithfull Amer-Nat 55 Blade Screw Pitch Gauge Set

The Faithfull Amer-Nat 55 Blade Screw Pitch Gauge Set is a professional measuring tool designed to quickly and accurately determine the pitch of various screw threads. This comprehensive gauge set is an essential addition to any engineer's, machinist's or mechanic's toolkit, helping identify both metric and imperial thread specifications with confidence.

Manufactured from high-quality polished tool steel, this screw pitch gauge features 55 clearly marked leaves that cover an extensive range of thread sizes. The gauge measures US National 60 degree threads from 4 to 42 threads per inch (tpi), whilst also accommodating metric 60 degree threads ranging from 0.25mm to 6.0mm pitch. This dual measurement capability makes it particularly valuable in workshops handling both imperial and metric fasteners.

Each leaf is clearly marked with its corresponding size, eliminating guesswork when matching threads on bolts, nuts, studs and threaded components. The gauge incorporates locking devices at both ends to securely hold the leaves in position during use, preventing accidental displacement and ensuring accurate measurements. Ideal for maintenance engineers, machinists and mechanical fitters working with diverse thread standards, this gauge set streamlines thread identification tasks and helps prevent costly fastener matching errors.
